ParseSession

Parse~ ParseSession

A Parse.Session object is a local representation of a revocable session. This class is a subclass of a Parse.Object, and retains the same functionality of a Parse.Object.

Constructor

new ParseSession(attributes)

Parameters:
Name Type Description
attributes Object

The initial set of data to store in the user.

Extends

Members

attributes

Prototype getters / setters

Overrides:

createdAt :Date

The first time this object was saved on the server.

Properties:
Name Type Description
createdAt
Overrides:
Type:
  • Date

updatedAt :Date

The last time this object was updated on the server.

Type:
  • Date

Methods

(static) current() → {Promise}

Retrieves the Session object for the currently logged in session.

Returns:
Type:
Promise

A promise that is resolved with the Parse.Session object after it has been fetched. If there is no current user, the promise will be rejected.

(static) isCurrentSessionRevocable() → {Boolean}

Determines whether the current session token is revocable. This method is useful for migrating Express.js or Node.js web apps to use revocable sessions. If you are migrating an app that uses the Parse SDK in the browser only, please use Parse.User.enableRevocableSession() instead, so that sessions can be automatically upgraded.
